Specification of Letters Patent.

Patented May 6, 1919.

Application filed September 24, 1917. Serial No. 192,859.

i To all whom t may concern:

and has special relation to the type of socalled plow which is shown anddescribed in my Patent No. 1,17 0,635, dated February 8, 1916, in whichthe earth working devices consist in a series of spading elementsmounted on endless chains and revolved faster than the progress of themachine over the ground. In my present invention I have improved theconstruction and operation whereby a more effective machine is providedand the cost of manufacture reduced by that certain novel constructionand arrangement of parts to be hereinafter particularly pointed out andclaimed whereby the manual operation of a spade in thrusting straightdown into the 4ground and then turning to the horizontal position to cutout and break up the soil is more effectually approximated and the soilis broken up and pulverized and not merely turned over as in plowing. i

My machine, therefore, is in reality a motor spading machine `which digsup the ground, turns it over and pulverizes it in a single operation,rendering the "soil as line and smooth as if it were both plowed andharrowed, so that the ground is completely prepared for planting with asingle passage of the machine over the iield. i One of the importantfeatures of my improved `machine consists in the use of triangularshaped sprockets in which the sprockets for each set of spades arebrought close together and by preference in a vertical plane so thatiforeach of the endless chain spading elements only five links are required.With this construction, I am able to avoid any tendency of the spadingelements to drag or scrape as the machine moves over the ground, thusrequiring less power to propel the machine. t At the same time the smallnumber oflinks in `the `endless chain permits of a much more compactdesign,1 and so much vibration is` obtained in the use of suchthree-sided sprocketsthatzthe earthis `apart by `spacing sleeves 2?.

shaken from the spades and chains and the parts kept practically clean`without the necessity of employing any scraping elements intermediate`the series of endless chains.

In the drawings,

Figures 1, 2, 3 and 4 are side elevations of the triangular sprocketsand chain links with the spades showing the parts in four successivepositions which are assumed in the counter` clockwise rotation oftheparts, beginning with Fig. 1 and ending with Fig. 4.

Fig. 5 is a side elevation, and Fig. 6 a top plan view of one of thechain links with the spade attached. i

Fig. 7 is a side elevation, and Fig. 8 a* front elevation of one of thesprocket elements. y y i Fig. 9 is an end elevation, and Fig. 10 a frontelevation of the sprockets showing the method` of mounting same on thecarrying shaft.

y Fig. 11 is a side elevationof the rear half of the motor plow.

As in my former patent, the entire implement comprises two substantialframes, a front frame carrying a motor and supported on an axle uponwhich is mounted the front carrying wheels of the machine, and a rearframe in which the cultivator mechanism and rear carrying wheels aremounted. The

rear framework is indicated at 1, and the carrying and driving wheels at2, these Wheels being driven bythe motor driven shaft a carrying apinion b engaging the internal teeth c on the carrying wheels.

. Journaled insuitable `journal boxes 4: in the sides ofthe frame 1 arehexagonal shafts l, 121 and on these shafts are strung the triangularsprockets 2b which are spaced The face of each triangle is preferablysomewhat concave and is of a length substantially the length of onelinkof the spading elements. Upon each face of the sprocket are formedsemi-circular teeth or lugs 4a which engage the slotted portions of thelinks of the chain,

and the faces of the triangularsprockets are chains of five links eachtraveling over the `same numberof sprockets on the two shafts.

Of course, for larger or smaller machines, i

' the number of sprockets and endless chains the sprockets can bereadily and easily secured in place.

In mounting the sprockets in series, every other sprocket is set so asto bring the sprocket teeth in a different position for the alternateseries, asindicated in the end elevation (Fig. 9).

The chains are made *up each withf-ve large links 5, with the centralportion open to leave a space 6 for engagement with the teeth orv lugs4a, and each link has one bifurcated end 7 'and a boss 8 at the otherend for pivotal engagement between the bifurcated ends of the next link.In view of the factthat the teeth on the sprocket are semicircular, theywill enter'the links without jarring, grinding ,or undue friction, whichis of lparticular importance in view of the sharp turn required byreason of the fact that the sprockets are triangular.

As already described, the sprockets are set in like position for eachchain, but in dii'erent positions for the series. Thus in F 'g. 1, eachsprocket has an angle pointed upward and a lat'side downward. Fig. 2shows the two sprocketsy at 30o from their n position in Fig. 1; Fig. 3at 300 from Fig. 2'; and Fig. l at 30O from Fig. 3. The links havelocated at the forward end thereof a flat tongue 9 extending at a littleoff the parallel with the link. The'upper or outer side'of each tongueis reinforced by a curved buttress 10, andthe spades are to be attachedto the flat under side thereof. These spades' 11 comprise blades of thedesired length demountablysecured to the tongues by means of bolts 13 orin any other desired manner.v One machine may be furnished with diierentlengths of spades for diiferent types of work. 4The spades extend inline with the under sides of the tongues.

"The vibratory movement of the chains which results in throwingv on" theadherent soil can be seen by following'the Yspade indicated at A inFigs. 1 to 4L. In Fgl, it will be seen that the spade at A is quite farfrom the center line connecting the axis of the two drums. In Figs. 2andV 3, it is considerably closer, and in Fig. 4: it is back againy atthe full distance. j

lThe digging movement `can be observed b following the spade indicatedat B in Figs.

'1;to'14. vIf itis remembered that the machine is lmoving alongin theopposite direction to the movement ofthe spades in digging, ,it f, ywillloe understood gthat' vallov'ving for-this mbv ement tl'ie"y spades Aarethrust fs'uloy.upwardly the earth which has been dislodged as seen at Bin Fig. 4.

In order that the soil thrown back by the spades may not becomescattered and to more effectually break up and pulverize the ground, Ihinge to the rear frame at 1+i a fall-board 15 which, when the machineis at rest, takes a substantially vertical position but, as the dirt isthrown up against it when the machine is in use, the board swingsoutwardly under the pressure of the material into an angular position.lhe fall-board thus, as it were, floats on the soil thrown up againstit, allowing clods to be broken and generally the material moreeffectively pulverized and evenly distributed.

I also provide a cover 16 to bridge over the space between thefall-board and the front portion of the machine so that the spadingdevices are effectively covered in the finished machine.

I have found from many tests made of the machine above described thatone passage of the machine over the ground will dig up the earth to thedepth of the usual plowing, thoroughly mix the dug-up soil, break itinto tine particles, and leave the pulverized earth in a level bed,ready for planting. It is thus possible to use a planting machine as atrailer behind my motor plow, and plant and cultivate the field all atone time.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
